Abstract：

In the actual production process for a certain type of 80 MN electric screw press, there is a large error between setting and actual values of strike energy, which leads to the increasing of energy consumption and affects the life of equipment. Therefore, an optimized calculation method for the strike energy was proposed. After analyzing the system structure and the operating principle of this press, under the premise for the original calculation formula of the strike energy, comprehensively considering the slider weight, energy attenuation and other factors, the optimized calculation formula of the strike energy was obtained for different usage conditions, and the key parameter in the formula of energy attenuation coefficient was accurately predicted in the short term by ARIMA model. The results show that the optimized calculation method for the strike energy greatly reduces the error between the setting and actual values and realizes the purpose of reducing the energy consumption and increasing the service life of equipment.
